Explain a market
How a country stacks supply, network charges, taxes and levies, who sets each layer, and which request parameters that makes essential.

AI Assistance
Two pieces that keep your AI tools and your team current on European electricity prices — no integration to build.
1 · MCP server
Your assistant explains the market
For Claude, Cursor or VS Code: how each market builds its price, which parameters a request needs and how to read a response — answered from our reviewed write-ups, not from training data.
How it works2 · RSS change feed
The feed tells you what changes
Every regulatory change to a component of the price, by country and date — in a feed reader, Slack or Teams, your calendar, your assistant or the cockpit.
What it covers1 · MCP server
Your assistant explains the market
The tounify MCP server lets an AI assistant answer questions about European electricity pricing and about integrating the tounify API — how a market builds its price, which parameters a request needs, how to read a response — from our reviewed market write-ups and live coverage figures instead of from its training data.
https://mcp.tounify.io
How a question reaches tounify
The server offers your assistant a set of tools — small, named abilities, each with a description of when to use it. You only ever ask in plain words; the assistant reads those descriptions and picks the tool itself.
- 1
You ask
In plain words, in Claude, Cursor, VS Code or any assistant that speaks MCP:
“Why does Germany need a grid tariff?”
- 2
Your assistant picks a tool
It matches your question to the tool whose description fits:
explain_country_pricing - 3
tounify answers the tool
From our reviewed market write-ups and live coverage figures — not from the model’s memory.
- 4
You get the answer
Your assistant replies in its own words, grounded in what tounify returned.
The tools, and a question for each
Each card is one tool: what it does, a question that makes your assistant use it, and the tool's name — the label your assistant shows in its activity while it works. Try any of the questions once you are connected.
Explain an API concept
What a parameter, a response field, a unit or a plan term means, answered from the published reference.
“What does include=fees add to a day-ahead response?”
Tool your assistant callsexplain_api_concept
Check a request before you send it
Flags the requests that would return a valid-looking but incomplete price, such as a missing network layer.
“I'm about to request German day-ahead prices with just a consumption tariff and include=fees. Will that give me the full price?”
Tool your assistant callslint_dayahead_request
Diagnose a response
Explains an error status, an empty series or a price that looks off, and says what to change.
“I'm getting 400 unknown tariff id, but I copied the id from your companies response.”
Tool your assistant callsdiagnose_response
Check coverage
Whether tounify holds data for a country and tariff direction, read live rather than from memory.
“Do you cover Polish grid fees?”
Tool your assistant callscheck_coverage
Describe a connection
Which properties of a customer's grid connection matter in a country, and the values each can take there.
“Which details of a household connection matter for prices in Austria?”
Tool your assistant callsexplain_connection_properties
Plan an integration
The ordered calls for your country and use case, with the polling rhythm and what to assert on.
“Which calls do I need to show tomorrow's hourly prices to Dutch households?”
Tool your assistant callsbuild_integration_recipe
Size your plan
Turns a described integration into a monthly call estimate and the plan that fits it.
“5,000 heat pumps polling hourly — which plan do we need?”
Tool your assistant callsestimate_usage
Keep it working
Writes a CI test that catches a missing price layer or a retired tariff before your users do.
“How do I stop my integration breaking silently?”
Tool your assistant callsgenerate_integration_test
Track regulatory changes
What changes in a country's taxes, levies, VAT and network charges, from which day, and by how much — on plans that include the change feed.
“What changes in the Dutch electricity price on 1 January?”
Tool your assistant callslist_regulatory_changes
Good to know
- It works with your tounify account: your assistant asks you to sign in once and approve the connection, and clients without a sign-in flow send one of your API tokens instead.
- Every account gets a free allowance of tool calls; the plans whose pricing card lists the MCP server include it without limit.
- Read-only: it explains, checks and plans, and never returns electricity prices — those come from the REST API.
- On plans that include the regulatory change feed, one tool also states the regulatory figures behind each dated change, one component at a time.
- Do not paste credentials or personal data into a question.
How the MCP server handles data is described in the privacy policy.
2 · RSS change feed
Know every regulatory price change before your users do
The tounify change feed tells you, country by country, every regulatory change that moves a component of the electricity price — a tax, a levy, VAT, a network charge, a regulated retail price, a time-of-use window — from which day it applies, what it was and what it becomes, and whether our API already serves it. It reaches you where you work: a feed reader, a Slack or Teams channel, your calendar, your assistant, or the explorer in the cockpit.
Not just a news feed
One record behind your API, your assistant and your inbox — so what you read, what you ask and what you bill all agree.
- API
The same figures your API serves
Every amount is the figure our API serves, net of VAT unless it is a rate, and each change says from when the API serves it. Your news and your prices never disagree.
- MCP
Your assistant knows it too
Ask your assistant what changes in a market, or at a site by its postal code, and from which day: the MCP server answers from the same record, with the figures.
- Cockpit
Browse it, no integration needed
Look up any change by market and component in the cockpit, and save the view as a feed for a channel, a calendar or your own code.
- Calendar
Plan ahead, don’t react
Every announced change ahead, its effective day in your calendar, and five years of history behind it for every market we serve.
Where it reaches you
RSS / Atom
Subscribe in a feed reader, or post every change into a Slack or Teams channel.
Calendar
Every effective date as an all-day event in Outlook or Google Calendar.
JSON
The same records for your own code or an automation in Zapier, Make or n8n.
MCP
Ask your assistant what changes, where and when — it answers with the figures.
Cockpit explorer

What the feed holds — a preview
The changes coming up and just in force across every market as header lines, and changes from more than a year ago in full. The cockpit opens every change, with its figures and source.

Electricity excise restructured and lowered to offset the VAT change on the standing charge
The finance law for 2025 split the electricity excise into a base rate and a uniform surcharge that funds the price equalisation for France's non-interconnected territories, moved the funding of rural electrification from the network tariff into the excise, and lowered the excise to offset the end of the reduced VAT rate on the standing charge.

New balancing-capacity charge on every kilowatt-hour consumed
After the Baltic grids synchronised with continental Europe in February 2025, the transmission operator AST buys balancing reserves on a joint Baltic market. From July 2025 consumers pay their share: a portfolio component on all consumption, set by AST, and an imbalance component that depends on each supplier's own imbalance and stays in the supplier's price.
